Answer:
Explanation:
Direction of velocity of electromagnetic wave is given by the formula
E = E j ( vector form )
B = - Bi ( vector form )
Direction of velocity = direction of vector E X B
= E X B
= E j x -Bi
= - EB -k
v = EBk
So the direction of velocity will be along z direction.
The answer you are looking for is 22 mph.
Solution:
s=speed
d=distance
t=time
Setting up the formula for the speed of an object with distance and time:
s=d/t
Substituting the given values,
s=88 miles/4 hours
So, therefore, the final answer is 22 mph.
I hope this helped answer your question for you. Good day to you.
Answer:
Depth is 7.49cm
Explanation:
Given that;
The diameter of tube is (D)=4.7cm
Area of the tube is =πD^2/4
Area is 3.142*4.7*4.7/4=17.35cm2
Mass(M)=130g
Density =1g/cm^3
Recall that Density =mass /volume
Hence volume =130/1=130cm^3
Also note
Volume=area*depth
130=17.35*depth
Depth=130/17.35=7.49cm
1) The correct answer is CME:
In fact, CME stands for "Coronal Mass Ejection", and they are huge release of plasma and magnetic field from the corona of the Sun.
2) The only statement that could be true is "<span>X and Y are both within the solar system."
In fact, the distance between X and Y is 30.2 AU (1 AU is the distance between Earth and Sun). Pluto, the farthest planet from the Sun, is located at approximately 40 AU from the Sun: the distance between X and Y is smaller than this value, so they could be both in the solar system.</span>
